From the project

This repository aims to detect fires at an early stage and classify the type of fire using sensor-fusion techniques and machine learning. The project is from the University of Texas at Austin's engineering senior design group Spring 2026.

Git on the jetson is setup using the SSH key route. Any git actions will not prompt a log in due to the stored SSH deploy key. Pushes will be recorded as have been made by the deploy key. Whoever is registered on the jetson's git config global user.email will show up as the user responsible of a commit at the time of commit.
